In a group of friends, the one friend that is kept there as a backup, they do just enough to keep him/her around. Only to to stuff with when the usual crowd of friends can't. Like the spare tire on the back of your car.
Scott: Crap I've got 3 tickets and only Jake and Connor can go, Tanner said he couldn't go. I guess I'll have to see if Luke can go instead since we've got no one else.
Scott: Hey Luke want to go with us?
Luke: I guess so. Looks like I'm 5th wheeling as usual.

R on Wheels is a retard on wheels. It is a person who acts like a retard, so you ignore that person. They are usually in a blow off class fooling around or making fun of other people when they have no friends. The most comman case is with freshman because they think that acting out this way will make them tons of new friends. When in actuality noone likes them for it.

The act of having been wheeled (lip kissed) by a tank (i.e. a person who has a robotic disposition).
Although it may be hard to detect whether or not a person has tank wheels, here are some major indicators:
1) when approaching their victim, they tend to move as though on a train track
2) when cock-blocked, they emit steam from their ears
3) once they've reached their destination (i.e. their victim) they say "Choo! Choo! All aboard!"
